Wall-flow water distributor used in water cold accumulation system

Abstract

The invention provides a water-flow water distributor used in a water cold accumulation system and belongs to the field of energy accumulation. The water cold accumulation system comprises a cold accumulation pool, the water distributor comprises an annular pipe, the annular pipe is fixedly connected to the inner wall of the cold accumulation pool, multiple water guide pipes are communicated to one side of the annular pipe, one end of each water guide pipe is communicated with the annular pipe, the other end of each water guide pipe is upwards arranged and is communicated with a cylindrical water distribution box, the water distribution box is provided with a cavity in the inside, the edge position of the side face of one side of the water distribution box is communicated with the water guide pipes, a water inlet is formed in the other side of the water distribution box, a flow dispersing portion protruding from the inner wall of the bottom to the top of the water distribution box is arranged in the water distribution box, a flow dispersing groove is formed in the top of the flow dispersing portion, the flow dispersing portion is located in a zone defined by the connecting positions of the water distribution box and the water guide pipes and is located under the water inlet, and a plurality of gaps are formed in the side, facing the cold accumulation pool, of the annular pipe and are tightly attached to the inner wall of the cold accumulation pool. The water-flow water distributor enables water to evenly, stably and slowly flow into the cold accumulation pool.

Description

technical field [0001] The invention belongs to the field of energy storage, and relates to a wall-flow water distributor in a water cold storage system. Background technique [0002] Water storage technology uses the difference in peak and valley electricity prices to store cooling capacity in water during low electricity price periods, and use stored low-temperature frozen water to provide cooling for air conditioners during peak hours of electricity consumption during the day. When the use time of the air conditioner is synchronized with the use time of the non-air conditioner and the peak and trough of the power grid, the power consumption of the air conditioner in the peak time of the power grid can be transferred to the trough of the power grid to save electricity. The most mature and effective cold storage method currently used is natural stratification. [0003] Natural stratification is temperature stratification. Temperature stratified water storage uses the physi...

Problems solved by technology

[0007] The object of the present invention is to solve the above-mentioned problems existing in the prior art, and to provide a wall-flow water distributor in the water storage system. The wall-flow water distributor can achieve uniform and stable water flow, and the flow rate slowly enters the cold storage tank, which solves the problem of uneven distribution of water flow in the water distributor in the existing water cold storage, which will disturb the thermoclinic layer and cause cooling capacity loss.
